Abstract

A pressure drum used for water cleaning apparatus is composed of the butt connected upper semi-drum with water inlet and outlet and lower semi-drum with aerating inlet, a plastic membrane with circumference clamped between upper and lower semi-drum, and a surficial plastic layer formed by injection moulding. Its productive technology includes such steps as preparing upper and lower semi-drums and plastic membrane by respective injection moulding, assembling and preparing surficial plastic layer by injection moulding.

Description

technical field [0001] The invention relates to an auxiliary part of water purification equipment and its production process, in particular to a pressure barrel used for water purification equipment and its production process. Background technique [0002] Water purification equipment that uses membrane methods to purify water has been more and more widely used. The main part of this kind of water purification equipment is a membrane tube with a membrane module, and a pre-filter device is provided before the membrane tube, and the water to be purified is pretreated by the pre-filter device before entering the membrane tube for reverse Osmotic treatment. [0003] The membrane tube is usually connected with a pressure barrel, the pressure barrel is formed by the upper half barrel and the lower half barrel open facing butt joint, the upper half barrel is connected with the membrane module through a pipeline, the switch valve is arranged on the pipeline, and the lower half barr...
